SHIFTING RAIL.

SPECIFICATION formingpart of Letters Patent No. 274,174, dated March 20,I883.

Application filed April 21, 1882. (No model.)

To all whom it may concern Beit known that I, 0. CHESTER GoGGINs, a

citizen of the United States, residing at New Seat Rails, of which thefollowing is a specification, reference being had therein to theaccompanying drawings, in which- Figure 1 is a view of a carriage-seatand of Fig. 2 is an enlarged view of the back rail and of the knobs forholding the back quarters of the top and also the back curtain. Fig. 3is a vertical and longitudinal section of the back rail. t

My improvement relates to carriage-seat rails. its object being to makea rail that is easily adjustable to seats of different lengths, and arail to which the top may be fastened in such amanner as to be removablewith the railfrotn the seat.

To this end theimprovement consists in the construction and arrangementof parts, as hereinafter more fully set forth.

To enable others to make and use my improved rail, I will describe it indetail.

A is the seat, to which the adjustable rail is fastened by screws orother suitable means. The similar side rails, B and C, have the parts aand b, to. which the top is attached, and also the parts indicated bythe letter a, for fastening them to the seat. Their back ends are bentat right angles and enter the tube D, and are held in the tube by theset-screws e. The tube D has the knobs o, to which the back quarters, asthe back pieces on the sides of the curtain are called, are fastened, sothat the. top is removable with the rail. As ordinarily constructed, theback quarters are attached to these-at and have to be disconnect ed onthe removal of the top. By making the back rail long enough and byattaching the back quarters to it by suitable means, the

top is in no way disturbed or wrinkled by the adjustment of the siderails. The set-screws 0 may be threaded in the tube, or they may bethreaded in the side rails, and slots may be made in the tube to allowthe movement of the side rails for adjustment.

The construction may be somewhat varied without departingfrom the spiritof my invention. For example, theback rail, D, may be a longitudinalsection of a tube, except near its ends, where it is a tube; or it maybe a flat bar of iron with tubular ends.

I am well aware that various devices have been employed to makecarriageseat rails adjustable to seats of different lengths.

I am also aware that carriageseat rails have been made with tubularangle-couplings for uniting the side and back rails; that side railshave been rabbeted to wood backs, and that side rails have been attachedto back rails of different lengths, the adjustment to. seats ofdifi'erent lengths being made by a change of the back rail; but

What 1 claim as my invention, and secure by Letters Patent, is-

A shifting rail for carriage-seats, composed of the side rails, B C, andthe tubular back rail, D, the side rails having their rear ends bentinward at a right angle to enter the ends of the tubular rail, and beingheld adjust-ably therein by means of set-screws e e, and the back railbeing provided with means for securing the back quarters and backcurtain of the carriage-top, whereby they are removable together and therails capable of adjustment without disturbing said back quarters,substantially as shown and described.

In testimony whereofI affix my signature in presence of two witnesses.
